VENTILATIN G DEVICE.

Specification of Letters Patent.

Patented July 20, 1915.

Application filed November 11, 1912. Serial No. 730,685.

air for promoting an exhaust from the inclosure to be ventilated, which will be simple in construction and cheap to manufacture, which will not involve the use of movable or adjustable parts, but which, nevertheless, will be so constructed as to effectually prevent outside air, dust, rain, and the l1ke from being forced, driven or blown into the inclosure.

The invention has for further objects such other novel and improved constructions, arrangements and devices in ventilators as will be hereinafter described and claimed.

The invention is shown in certain typical embodiments in the accompanying drawings, wherein Figure 1 shows in elevation a ventilator of a type suitable particularly for railway cars, the view being taken from the front or rear of the car. Fig. 2 is a sectional plan on line 22 of Fig. 1. Fig. 3 is a vertical sectional view on line 33 of Fig. 2. Fig. 4 is a view, in elevation, of a modified form of ventilator adapted particularly for use upon buildings or other stationary structures. Fig. 5 is a plan view, partly in section, of the device shown in Fig. 4, and Fig. 6 is a vertical sectional view on line 66 of Fig. 5. y

' Like-characters of reference designate like parts in the several figures of the drawings.

Referring first to Figs. 1 to 3 inclusive, the ventilator, in the preferred form therein shown, consists of a box-like structure preferably made-of sheet metal, composed of a base 10, which, in the particular structure shown, is curved so as to fit the round ed deck or roof of a railway car, a top or outer end member 11,-end walls or air resisting faces 12, and side walls 13, the sideand end walls being spaced apart so as to form openings 14 at each corner of the structure. The base is formed with an opening '15 adapted to register with an opening in the deck of the car. Within the walls 12,

13, and substantially parallel thereto respectively, are walls 16, 17, theformer being provided with preferably centrally arranged openings 18 and formed at the'sides of these openings with the out turned deflecting flanges 19. The top member 11 is preferably formed so that it projects over the end faces 12 as indicated at. 20, Fig. 3. Preferably flanges 22 are provided at the intersections of the inner walls 16 and 17.

The device operates as follows: It is placed over an opening in the roof of the car with the end walls 12 facing the front and back of the car. When the car moves the air impinges upon these walls and is forced over the edges. thereof and through the air passageways 23 formed between the outer side walls 13 and the inner side walls 17.

This produces an exhaust from the interior of the car through opening 18 and the exhaust passageways 24 formed between the outer end walls 12 and the inner walls 16. The flanges 19 serve to prevent rain, dust, and the like, from being blown into the car through the openings 14, 18. The flanges 22 serve a like purpose. The overhanging rims 20 of the top member 11 check the tendency of the air to escape over the top of the ventilator instead of passing through the passageways 23.

The device has been described as placed over an opening in a substantially horizontal wall. Obviously the device might be adapted, by changes of a mere mechanical sort, to be placed against an opening in a vertical wall, for example, in'the clearstory or monitor of a carof that type. Other modifications in form and proportion might be made without departure from the principles of the invention.

In Figs. 4 to 6 inclusive, I have shown a modified construction suitable more particularly for use on a stationary structure, a

ferently constructed fromthat shown in Figs. '1 to 3. The structure is shown as 110 mounted upon a base or neck 25, although the inner walls are formed adjacent the openings 32 with the out turned flanges 33 and the outer walls are formed, opposite the openings 32, with the preferably \l-shaped bulges 34. The openings 32 bypreference do not extend down to the bottom member 26 nor do the flanges 33.

The device operates as follows; It is placed either over an opening in a horizontal wall or roof, that is, in the position shown in the drawings, or may be placed horizontally with the base or neck 25 registering with or projecting'through the opening in a vertical wall. In either position the wind, nomatter in. which direction it may blow, will produce a draft through one or more of the pasageways35 between the walls 29, 31, and this draft will exhaust the air from the .inclosed space to be ventilated through the openings 32, 27. The disposition of the flanges 33 prevents the air from blowing into the inclosure through the ventilator. The bulges 34 are primarily for the purpose of widening the passageways 35 opposite the openings 32 so as to prevent choking and back draft. The top or outer end member 28 projects beyond the walls 29 so that the air is intercepted and directed into the openings 30 and passages 35 instead of being allowed to escape over the top of the ventilator; The openings 32 commence at a point above the bottom member 30 so that water and the like which may enter the passageways 35 will not have a chance to get into the inclosure through the opening 27.

I claim: Q i 1. A ventilator of the character described comprising a box having imperforate outer end and side walls forming openings be tween their adjacent ends, a base containing an inlet opening, and a top, and a chamber within the box about said opening formed of side walls cooperating with said outer side walls to form air passages extending between said openings, and deflect- ,ing end walls provided with openings and forming with said outer end walls spaces crossed at their ends by said passages, for the purpose set forth.

2. A ventilator of the character described comprising a box having imperforate outer end and side walls forming openings between their adjacent ends, a base containing an inlet .opening, and a top provided with ledge forming extensions overhanging said end walls, and a chamber within the nuance comprising a box having imperforate outer end and side walls forming openings between-their adjacent ends, a base containing an inlet opening, and a top, and a chamber .within the box about said opening formed of inner side walls cooperating with said outer side walls to form air passages extending between said openings, and inner end walls having outwardly deflected-sections forming openings and shields at the bases of the openings, said inner end walls forming with said outer end walls spaces crossed at their ends by said passages, for the purpose set forth.

4. A ventilator comprising an air resisting surface and formed with an exhaust passageway co-extensive with said surface and communicating with the inclosure to be ventilated, and with an air duct extending from one edge of said air resisting surface across the end of said exhaust passageway and through the ventilator.

5. A ventilator comprising an air resisting surface and formed with an exhaust passageway comprising passages at substantially right angles to each other, communicating with the inclosure to be ventilated and communicating rectangularly with an air duct extending from one edge of said air resisting surface across the end of said exhaust passageway and through the ventilator. 6. A ventilator comprising an air-resisting surface and formed with an exhaust passageway co-extensive with said surface, and with an air duct substantially at right angles to the exhaust passageway extending from one edge of the air resisting surface across the outer end of said exhaust passageway and through said ventilator.

-7. A ventilator comprising an air resisting surface and formed with an exhaust passageway comprising passages at substantially right angles to each other, and communicating rectangularly with an airduct substantially transverse to the outer end of said exhaust passageway extending from one edge of said air resisting surface across the outlet of said exhaust through the ventilator.

8. A ventilator comprising a box-like structure having a base provided with an passageway and opening adapted to communicate with the 1 substantially parallel with said surfaces,co- 1w extensive therewith, and formed with openings, and inner walls substantially parallel with said side walls.

9. A ventilator comprising a box-like structure having a base provided with an opening adapted to communicate with the inclosure to be ventilated, an outer end, side walls spaced apart so as to provide outlets, and inner walls providing rectangularly disposed passageways through said ventilator,

- said inner walls each formed with a central inclosure to be ventilated, an outer end, side walls spaced apart so as to provide outlets, and inner walls providing passageways rectangularly disposed through said ventilator, said inner walls each formed with a central opening, and said outer walls being formed with bulges opposite the openings in the inner walls.

12. A ventilator comprising a box-like structure having a base provided with an opening adapted to communicate with the vinclosure to be ventilated, an outer end, side walls spaced apart so as toprovide oulets, inner walls providing passageways rectangularly disposed through said ventilator, said inner Walls each formed with a central open ing, and with outwardly projecting deflecting flanges at said openings, and said outer walls being formed with bulges opposite the openings in said inner walls.
